We look at the division of 920857 by 63 
The aim is to understand the frequency of 63 in 920857.

On to step 1:
63 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 63

On to step 2:
If we divide 92 by 63, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 29 after subtracting 63 from 92.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 63

Advancing to step 3:
63 can be fit into 290 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 252 from 290, we get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 63

Let's proceed to step 4:
The number 63 fits into 388 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 146.0
Subtract 378 from 388 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 63

Let's proceed to step 5:
The number 63 fits into 105 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
Subtract 63 from 105 to get 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 63

Advancing to step 6:
427 divided by 63 is 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 14616.0
Subtract 378 from 427 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
If we divide 490 by 63, we get 7 and a remainder of 49.
The next digit of our result is 7. 
Result so far: 14616.7
Deduct 441 from 490 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
490 divided by 63 is 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 14616.77
Subtracting 441 from 490 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

In conclusion, the division gives 14616.77 with a balance of 0.049.
